Moin Moin. I have a Böckmann Classic horse trailer Bj 92 full-poly since Monday. Now I have to go to TÜV on Friday. I have never been with a trailer at the TÜV. What do I have to pay attention to or what is the TÜV paying attention to. Is the tailgate relevant? It is rather rotten. What leads to further questions. How strong is the tailgate? I have to install a new plate. Is the outside front painted or is it also poly? I know this is quite a lot at once but if we could pick it apart. ?? It would be very nice if you would help me.
